Okay, I've got some problems and have had it for over a month now...

1) Computer takes 3+ minutes to shut down.
2) Sometimes a blue screen will appear and say physical dump of memory, and says the cause can be new installed software (Haven't downloaded or installed in anything in forever).
3) Sometimes everything will maximize in size.

Now I've ran Crap Cleaner, Spybot, and Norton Anti-Virus and nothing out of the way shows up... Anything tips on what I should do?
